My research activities entail a broad range of topics in climate variability and climate change. I focus primarily on surface-atmosphere interactions, over both the land and the oceans. One of these research areas investigates changes in high-latitude and high-altitude environments; specifically, the interactions between frozen ground (permafrost and seasonally frozen areas) and other cryospheric variables in the high latitudes of Eurasia, with the overlying atmosphere. Some of my other research studies the effects of land cover and land use change on climate across the Tibetan Plateau and China.

I also continue to explore ocean-atmosphere interactions in both the tropics and midlatitudes, such as interactions between the Pacific Ocean and synoptic-scale atmospheric circulation variability of the Northern Hemisphere. Additionally, I am evaluating climate patterns and atmospheric teleconnections, in terms of both their general variability and climate change.
